Creating a Rails Edge App

So, I decided to create a Rails Edge app today to run some tests against the latest upcoming release.
As per the Rails Guides,
all that should be required to create a Rails app is the following command:

rails new myapp --edge

However, things didn't work out as planned. Bundler was failing due to some type of dependency problem.

I did not even try to figure out the source of the problem. I simply choose a workaround. All you need to do is use git to clone the rails repo
and run the rails executable under the railties/bin directory coupled with the same parameters you would normally pass to create a Rails Edge App.

Create a work directory and change to that directory.

mkdir -p /tmp/work
cd /tmp/work

Clone the rails repo.

git clone git://github.com/rails/rails.git

Make sure you checkout the latest stable release.

# you just cloned rails. change to that directory
cd rails
# this will generate a list of all the current tags.
# choose that latest one from the list.
git tag
git checkout v3.2.2.rc1 (or whatever is the latest release)
# now, change back one directory.
cd ..

Create the Rails Edge app using the following command.

rails/railties/bin/rails new myapp --edge

I have two videos. One that shows the failure and the other that shows the success. Both of the links are at the top of this post. Please keep in mind
that I am an authority of nothing; I simply got this to work.
